Actor/comedian Louis C.K. appeared on
"The Tonight Show" Monday (May 12), where he talked with host Jimmy Fallon about the last time he was supposed to do Fallon's show, which was "Late Night" at the time, but Fallon had to cancel.

It turns out it was because his daughter Winnie was being born, so they didn't tape a show that day. But the producers who called Louis C.K. were incredibly circumspect about the show being canceled, because Fallon and his wife had been keeping their surrogacy on the down-low after many years of unsuccessfully trying to have a baby.

But based on how sketchy the producers were being, C.K. says he was convinced he was going to see on the news that night that Fallon had died.

"Sorry to scare you like that," says Fallon. "I wasn't scared, I was just curious," says C.K. with a laugh.

Below, C.K. talks about boating around the island of Manhattan because he owns a boat. But one time he decided to go out into the ocean just to see how that would go, and all of a sudden some fog rolls in and C.K. almost got hit by a Norwegian freighter. Yikes.

Finally, C.K. talks about his FX comedy
"Louie," which took 19 months off between Season 3 and Season 4, which he says is because he wanted to make the show the best it can be.

"This year I spent a year making the show. ... The reason I took a year off was so I could make the show better. It's the hardest I've ever worked on the show," says C.K. and he shows off a clip that's based on a real-life rule he and his daughters have about riding the subway.
